![]() ![]() The matting and miners moss underneath the sluice’s riffles are the same. With a highbanker, the water is supplied by a pump rather than the flowing water of a stream. Sluice: High bankers utilize a normal sluice to recover the gold from the gravels, and the operation of the sluice box portion of a high banker is basically the same as that of a hand or stream sluice. The spray water comes out under a lot of pressure and washes any loose sand or clay into the sluice and also provides part of the water needed to move material through the sluicebox area. Some rocks may hang up, but for the most part, they will slide off on their own. The slats should be set on an angle so that most of the larger gravel will slide off the slats by the pull of gravity without you needing to push them off by hand. The large rocks that are caught by the grizzly are washed with the spray and then rejected. A series of rods are arranged to make a slat-type screen (called a grizzly) that allows water and smaller material to fall through and go down into the sluice box. A water valve located ahead of the spray pipe controls the amount of water flow going into the feed box sprays. The water is normally sprayed from simple plastic pipes with a series of small holes drilled into them. Hopper: The feed box contains a grizzly screen with a water spray bar. They have three main components: a hopper feed box, and sluice box, and a pump. High bankers are fairly simple to set up and operate. ![]() That also means it will likely be heavier and less portable. The bigger the unit, the more gravel it will handle in a day. High bankers are available in various sizes. Just shovel material directly into a high banker and let the equipment do the rest of the work! As long as there is sufficient water close by so the hose can reach it, you’ll be good to go. The optimal place to use a high banker is a location along a river where there are lots of bench gravels that have been left high and dry by erosion. Their main use is to allow you to pump the water to the gravels rather than carrying heavy buckets of gravel to the water. A highbanker, sometimes called a power sluice, is a very flexible and efficient piece of equipment when you’re gold mining in areas with a good amount of water.
